Tecaform™ Acetal Copolymer

TECAFORM™ is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.

TECAFORM™ is a semi-crystalline thermoplastic offering high strength, stiffness and toughness. TECAFORM™ is resistant to hot water, hydrocarbons and solvents, and it possesses good bearing and wear properties. It is available in natural and black grades. TECAFORM™ is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.

No centerline porosity

Low moisture absorption

Excellent machinability

Good combination of mechanical properties

Chemical resistance to fuels and solvents

TECAFORM™ is resistant to aqueous solutions with pH values
ranging from 4 to 14.

Good wear and abrasion properties

Natural grade is manufactured from resins that are FDA, USDA, NSF and 3A Sanitary compliant

Good dimensional stability

Good property retention at elevated temperatures

Black Grades are also manufactured from resin that is FDA compliant

TECAFORM™ is used in a wide variety of industrial applications requiring good strength
and toughness, dimensional stability, wear resistance and the ability to operate in a wet
environment with little absorption. Material handling, machinery and fluid handling are
some of the common industries utilizing TECAFORM™ ’s combination of properties.
Typical applications are gears, wear strips, bushings, pump parts, fittings and rollers.
